Member Function Documentation

virtual HD_API size_t HdNullBufferSource::ComputeHash ( ) const
overridevirtual

Computes and returns a hash value for the underlying data.

Reimplemented from HdBufferSource.

Reimplemented in HdStExtCompGpuPrimvarBufferSource.

virtual HD_API void HdNullBufferSource::GetBufferSpecs ( HdBufferSpecVector specs) const
overridevirtual

Add the buffer spec for this buffer source into given bufferspec vector. note: buffer specs has to be determined before the source resolution.

Implements HdBufferSource.

virtual HD_API void const* HdNullBufferSource::GetData ( ) const
overridevirtual

Following interfaces will be called after Resolve.

Returns the raw pointer to the underlying data.

Implements HdBufferSource.

virtual HD_API TfToken const& HdNullBufferSource::GetName ( ) const
overridevirtual

Return the name of this buffer source.

Implements HdBufferSource.
